Application filed 'June so,

which the following is a specification.

- This invention relates to horseshoes, and to that class having detachable calks.

The object is to provide a horseshoe having means for receiving and rigidly holding heel and toe calks in such manner as to prevent their accidental dislodgementunder the severe strain to which they are subjected in use, and to readily permit'of their re moval when they become worn for the purpose of replacing themwith new calks.

Another object is to provide, for such a horseshoe, interchangeable calks, the one form. being adapted for use on snow or slippery roads and streets, and, when desired, the same may be removed and other calks suitable, for instance, for plowing or working' upon soft ground, may be substituted therefor, the holding means being the same for each form of calk.

A further object is to provide a shoe having these characteristics which may be formed of appropriate metal properly .heated and forged in one operation to form the shoe into proper contour, and having at the heel and toe, the necessary seats for accommodating the detachable calks together with the holding'meanstherefor, the particular form of the present shoe being such as to permit the co-operation of the dies and allow of their withdrawal from the metal after theishoe is formed. v p v c A full and complete understandingiof the invention may be obtained from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification; it being understood that while the drawing shows a practical form of the in- ..vention, thelatter is not tobe confined to strict conformity therewith, but may be in the county of Blair and with; and

Fig. 2 1s a longitudinal sectional view thereof; I

Fig. 3 1s a perspective view of the toe calk removed;

Fig. 4 1s a detail perspective view of the toe portion of the shoe and illustrating the seat of the toe calk;

igl5is a detail perspective view of the spring clip used to hold the heel and toe calks in place within the seats of the shoe;

Fig. 6 is a detail top plan view of one of the heel portions of the shoe and illustrat ingthe connection of the spring clip there- Fig. 7 is a detail perspective view of the alternate form of heel calk.

In Fig. l there is shown a horseshoe l havingthe usual shape and which, of course, may have any other of the well-known shapes, and may be of anysize, the same being providedwith the usual grooves 2 on the underside of the shoe, said grooves be ing punched at spaced intervals, in the usual manner, to provide nail holes 3 for the relarged boss 4 extending across the toe portion of theshoe and arranged transversely thereof, the boss being formed integrally with the shoe, and having its front wall in alinement with the front edge of the shoe and at right angles to thetop side of the same.

The boss 4 extends towards the ground when the shoe is applied to the hoof of the animal as will be understood, and is pro- .vided with an elongated, transversely disposed cavity or seat 5 open at its lower end and closed at its upper end by the round toe portion of the shoe proper. i

The rear wall of the boss el, or that wall towards the heel of the shoe is cut away at its central portion, as indicated at 6, and the said wall gradually increases in thickness towards its point of juncture with the shoe to give the same great strength and durability, as illustrated in Fig. 4 of the drawing.

The central cut-away portion of the rear wall of the boss, together with transversely disposed cavity 5, forms. a T-Shaped seat at the toe of the shoe for the reception of a toe call: 7, composed of a block of hardened steel having an elongated body portion 8 of a length and thickness to snugly fit the transverse portion of the seat, and of a depth considerably greater than the depth of the said seat so as to project therefrom, when the call: is placed in said seat.

The projecting portion of the call: is tapered and brought to a chisel edge 9 in the case of the one form of call: as illustrated in Figure 3 of the drawing, this being the calk for use upon ice, snow or slippery roads, as will be understood.

The call: 7 is provided with an integral, transversely disposed tongue or extension 10, arranged at right-angles and centrally there of, and of a width to snugly fit within the cut-away portion 6 of the rear wall of the toe boss 1, and when the calk is properly seated therein, the exposed face of said extension is substantially flush or in. line with the lower face of the shoe proper, and the tapered portion of the calk is the only part exposed thereof.

The exposed face of the extension 10 is provided with a transversely disposed V- shaped groove 11, and the upper face of the shoe at a central point thereof, is provided with a shallow seat 12.

A spring clip 13 formed of a strip of thin steel is adapted to be applied to the shoe in overlapping relation to the extension 10 in a manner to rigidly hold the callc in position within the seat, and said clip has its terminals bent at right angles to the body portion thereof, one terminal 1 1 comprising a tongue adapted to fit within the shallow seat 12 upon the upper face of the shoe, so as to lie flush with the top surface of the shoe, while the other terminal of the strip comprising the clip has a semi-circular loop 15 and the end of the strip is inwardly-directed and formed into a V-shape, as indicated at 1.6, for the purpose of snapping into the I-shape groove 11 of the extension upon the under side of the shoe, as clearly shown in Figure 2 of the drawing.

At the end of each rearwardly extending, curved. branch of the horeshoe a similar, though necessarily narrower boss 17 is integrally formed, and such boss is provided with the transversely disposed seat 18 and. having its rear wall cut away in the same manner as the toe seat for the reception of narrow heel calks 1.9, which are seated in the same manner and held in place by clips 20 formed identically with the toe clip.

When it is desired to remove any one of the clips for the purpose of freeing the calk held thereby, as when renewing or changing the same, it is only necessary to introduce the point of some sharpened or tapered instrument or tool into the loop 15 of the clip, when the latter may be easily pried from its position after the knife edge 16 is freed from its position within the groove 11, and the said clips may be easily locked in position to hold the calks in their respective seats by a few blows of a hammer to force them into place,

The calk 19, illustrated in Figure 'Qhas its free end blunt which has been found advisable for use when working upon soft or dry ground, and the same may be readily substituted for the tapered calks when de sired.

From the foregoing it will be seen that a simple and cheaply manufactured horseshoe has been provided which may be readily forged out of proper metal by a single operation, the shapes of the several seats being such as to readily free the dies in the process of manufacture, and that the calks, being substantially built and rigidly held within the seats of the shoe, are held therein by means which are easily manipulated to receive and hold the calks or to release the same when desired.

What is claimed is:

1. A horseshoe having on its undersid an enlargement or boss provided with a cavity therein, and a cut-away portion communicating with the cavity, a calk seated in said cavity and having an extension to fit said cut-away portion, and a clip adapted to engage respectively the shoe and said extension to hold the calk in place.

2. A horseshoe having on its underside an enlargement or boss provided with a transverse cavity, and a cut-away portion leading from the cavity, a calk adapted to be seated in said cavity and having an extension fitting in said cut-away portion, and a fastening means adapted to engage respectively the inner face of the shoe and said extension and hold the calk in place.

8. A horseshoe having on its underside an enlargement or boss provided with a cavity, and a cutaway portion leading therefrom, a calk adapted to be seated in said cavity, and having an extension fitting said cutaway portion, and a spring clip adapted to engage the said extension and said shoe t hold the calk in place.

l. A horseshoe having on its underside an enlargement or boss provided with a cavity, and a cut-away portion leading therefrom, a call: seated in said cavity, and having an extension fitting in said cutfaway portion, and a spring clip having its terminals en gaged respectively. with the inner face of the shoe and said extension.

5. A horseshoe having on its underside an enlargement or boss provided with a transverse'cavity, and a cutaway portion formed in the wall of said enlargement or boss and communicating with said cavity, a calk seated in said cavity, and having an extension fitting in said cutaway portion, said extension being provided with a groove, a seat provided in the upper or inner face of the shoe, and a clip adapted to span the shoe at the point Where the said extension is located, one portion of the clip being adapted to engage the seat in the inner face of the shoe and the other portion constructed to engage with the groove in said extension.

6. A horseshoe having on its undersidean enlargement or boss located at the toe there of and spaced bosses located at the heel of the shoe, cavities formed in the bosses and cut-away portions in one of the Walls of the bosses communicating with the cavities, the said shoe having seats formed in the top face thereof directly above the said cutaway portions, calks adapted to fit the cavities and to project downwardly therefrom and having rearwardly directed extensions adapted to fit the cut-away portions of the cavities and to lie flush with the lower face of the shoe, said extensions being provided with transverse grooves in their under sides, and spring clips formed of. a strip of metal bent intermediately to provide spaced, rearwardly directed members adapted to span the shoe and said rear extension, one member fitting in the seat on top of the shoe, the other member having an inwardly directed terminal to fit in the transverse groove in the extension of the calk to clamp the same in position, and the latter member having an intermediate loop to receive a tool to facilitate its removal.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

FREDERICK D. YOUNG.
